Figure 4 shows the configuration for voltage measurement.
A full scale input range of
±
10V can be accepted by the
ISC300. The two sense lines can be connected to give open
or short circuit detection. An open circuit will result in an
output of < –5.1V and a short circuit will give a < 0.1V
output. See the Applications section under Fault Conditions
for more information.
Figure 7 shows a possible circuit configuration using jump-
ers to select voltage or RTD operation.
ISOLATED SUPPLIES
The two isolated supplies available on the input side are
capable of supplying
±
11.5V min at 5mA. These can be used
to provide power for external front-end circuitry for addi-
tional signal processing. When using the isolated supplies, it
is necessary to decouple them as close to the device as
possible. 10
μ
F tantalum capacitors should be used. This will
also improve the signal-to-noise ratio.
